United Parcel Service Inc. is going to spend $16.5 million to double the size of its facility in Ft. Myers, Fla., so it can keep up with growth in southwest Florida.

The Atlanta-based package shipper (NYSE: UPS) said it plans to expand an existing sorting facility by about 30,000 square feet and will add a modern UPS customer counter to handle customer shipping needs. UPS will upgrade loading and unloading technology to increase the facility's sorting capacity from 6,000 pieces an hour to 13,000 an hour.
